Roger Ebert was a renowned American film critic, best known for his work with the Chicago Sun-Times. He was the first film critic to win a Pulitzer Prize for Criticism in 1975, which solidified his influence in the world of cinema. Ebert's reviews were widely read and respected, making him a prominent voice in film criticism. In addition to his writing, Ebert co-hosted the popular television show Siskel & Ebert with fellow critic Gene Siskel. The show popularized the "thumbs up, thumbs down" rating system and helped bring film criticism to a broader audience. Ebert continued to write and review films until his passing in 2013.
